IRA M. WOODMANSEE, OE"` ST. LOUIS, MISSOURI,` ASSIGINR,` TO ALBERT n. cHArrfEnL,

OF ST. LOUIS, MISSOURI.

p To all 107mm t concern Be it known that I, Ina M. lVoonMANsEE, a `citizenof the United States, residing at the city of St. Louis, State of Missouri,

have invented certain new and useful I1nings, forming a part hereof, in which- Figure 1 is a side elevational View of a lubricating device embodying my invention; llig. 2, is a front elevational View of the same; Fig. 3 is an enlarged vertical sectional view through the same; Fig. 4t is a detail sectional view on the line l1t, Fig. 3; and Fig. 5 is an enlarged detail sectional view on the line awo, Figi.

"This invention relates to certain new and useful improvements i `in lubricating devices especially adapted and designed for use in connection with steam-engine valves, pistons, and cylinders, the objects` of my invention being to provide a device of thekind stated wherein the supply 'of lubricant for the engine parts to be lubricated may be readilyregulated or controlled `and the supplied lubricant preferably heated to an ap* proximately highv degree 0f temperature substantially uninterruptedly carried `and conducted by and with the steam supply to the engine parts to be lubricated, and to improve generally upondevices of the kind described. i

lVith the above and other objects in view,

`my present invention resides incertain novel features of construction, arrangement, and combination of parts, all as will hereinafter be described and afterward pointed out in the claims. t

` Referring to the accompanying drawings, in which` like reference characters refer to like parts throughout the several views, 1 indicates a preferably cylindrical reservoir l or tank for thelubricant, tank 1 being provided preferably at its upper end with a li'lbricant-supply opening 2 having preferably a bell or funnel-shaped mouth 3 and adapted to be closed by a threaded plug or the like 4:; Threaded into the lower end, and communicating with the interior, of tank l is a short section of pipe communicating through aT-couplingor the like 6, a cross pipe 7, and an angle `valve or the like 8` with l a water of condensation supply pipe 9 leading `from and communicating with a suit- Specification of Letters Patent.

able condenser 10, which, in turn, communi cates with one member of a suitable T-cou pling orthelike 11 threaded on a pipe 12 leading from the boiler or other source of steam supply, not shown.

13 indicates a substantially tubular memmember 13 being also provided with a lateral tubular extension la communicating with chamber a and which is adapted'to be threaded into tank 1 adjacent the upper end thereof and thereby aEord a lul bricant discharge-outlet or passage from tank 1 into chamber a. Leading at one, or its upper, end from chamber a, and extendlengthwise of, and centrally within, member 13, through its said chamber and` cross-walls 13 and 13, is an elongated lubricant discharge-nozzle 15 preferablyhav ing comparatively thin walls` and a bore of small diameter and discharging and termi nating at its other or lower end preferably 'somewhat `below the lower end of; said member 13, the supply of lubricant to and through said nozzle 15 being regulated or v controlled by a needle valve or the like 1G suitably mounted on member 13, as clearly seen in Figs. 3 and 5. Member 13 is further provided with a lateral boss or the like `17 provided interiorly with a by-pass 18 whereby, as seen clearly in Fig. `5, comimmication is had between said steam chambers l) and c of member 1.3.

Fitting in teriorly at its upper end in, and l communicating with, and forming substantially a part er continuation `of, steam chamber o of member 13, is a preferably glass or other transparent tubular member 19 having its lower end interiorly `fitting in, communicating with,

and supported by, a tubular member 2d in turn forming substantially a part or continuation of chamber c and supported in position byxmeans preferably of an `integral lateral boss 21 threadedinto tank 1, `as shown in Fig. 3. As also shown in Figx3, tube 19 'is preferably,removably held in communicatingposition between` members `13 and 20 bymeans of suitable packing nuts,

stuffing boxes, or thelike 22. Y Member 20 is s also provided with a lateral tubular extension 23 leading into, and communicating with, a tubular elbow or the like 241 which, in turn, is adapted to lead into or communicate with the valve casing and piston-cylinder of the engine to be lubricated.

Communicating at one end with coupling 11, as seen in F ig. 1, and leading there from downwardly and preferably laterally through a passage 1 provided for the purpose in tank 1, as seen clearly in Fig. 3, is a steam-supply pipe 25, pipe 25 Adischarging at its other end directly into the steam-inlet of chamber I) of member 13; and leading at one end from the` main steam-outlet of chamber b is 'a short section of tubing 26 forming substantially a continuation of steam-supply pipe 25 and leading at its other end into the upper end of said elbow 24, as shown in F ig. 3.

In operation or use, tank 1 is first supplied with a suitable lubricant L through its said opening 2. On rthe steam from the uboiler or other source of supplyl being permitted to fiow through pipe 12, a portion of such steam will flow through pipe 25 into chamber Z9 of member 13, where it divides and flows partly through pipe 26 and elbow 24 into the valve casing or; to the parts of the engine to be lubricated and 'partly through by-pass 18 into chamber @and its continuations 19 and 20 and from thence through lateral extension Q3 and elbow 24 also into the valve casing or to the parts of f Vthe engine to be lubricated. The other portion of the steam from pipe 12, on flowing into condenser 10, is there condensed, the water of condensation W thence flowing through supply-pipes 9 and pipe and their communicating connections, valve 8 being open, into tank 1, where it gradually forces or drives the lubricant L in tank 1 through said discharge outlet or passage 14 into chamber a of member 13, lubricant L thence flowing through the regulated bore of nozzle 15 into steam-chamber c and its extensions or continuations 19 and 20, where it7 in turn, is carried or conducted by the steam entering through said by-pass 18 into chamber c and its extensions 19 andZO directly through said lateral extension i3 and elbow 24 into the valve casing or to the parts of the engine to be lubricated. By providing the communicating steam chambers b and c and by so dividing the steam supply as I have described, it will be seen that I not only provide a suitable supply of steam to carry or conduct the supplied lubricant to the engine parts to be lubricated, but also thereby balance any back flow or pressure of steam there might be from pipe 26 and elbow 24 which might tend to retard or interrupt the proper flow of the lubricant from nozzle 15, the amount of lubricant flowing from nozzle 15v and so carried or conducted to the parts of the engine to be lubricated being regulated by valve 16 and clearly observed through transparent chamber-extension -19. `By passing steamsupply pipe 25 laterally through passage 1ft in lubricant-tank 1, as shown, the lubricant in tank 1 is somewhat that it will flow freely into chamber a. The lubricant on flowing through nozzle 15 is again or further heated by the steam in chamber b to substantially or approximately steam heat, so that, on entering chamber c,it

freely passes or is conducted, asL described,

heated so with the steam in chamber c to the `engine parts to be lubricated, the steam in chamber c being but slightly, if at all, reduced in temperature or condensed thereby. y

At its lower end member 2O is preferably closed by a removable plug or the like 27,

whereby not only may a broken or damaged tube 19 bereadily removed and replaced by a new .tube 19, but also, when necessary, surplus lubricant may be removed or drained from chamber c; and similarly T-coupling or member 6 is preferably provided with a petcock 28, whereby the water and remaining lubricant in tank lymay be removed or drained therefrom, valve 8 having` a wheel or manipulating-member 29 for regulating the flow of water from condenser 1() and pipe 9 into pipe 5 and tankl. I am aware that minor changes inthe several parts of my new lubricating device may be made and substituted for those herein shown and described kwithout departing from the nature and spirit of my invention. y
